If they go up i doubt it will be soley down to Hogan. From what i've seen of him, he is a woeful player and i don't expect smith to do anything with him. Tammy seems to be doing just fine.
I think the club realise that promotion is not looking too achievable currently and that thinking short term, like we did with Bruce, will just result in more mess needing to be sorted in the summer.
His freak injury allowed him to gain some much needed physical improvements and I think JT had more of an influence.
I seriously doubt Steve Bruce was vital for what we saw from Jack last year.
